In these formulations, surface active agents may be added to the formulations in order to make the formulations homogeneous and stable, if appropriate.
The content of the compound of the present invention as the active principle in the formulations is preferably in a range of from 5 to 70%.
The wettable powders, the emulsifiable concentrates and the flowable formulation comprising the compound of the present invention prepared as described above can be applied in a form prepared by diluting the formulations with water to the suspension or the emulsion at a desired concentrations, while the powders and the granules of the said compound can be directly applied to plants without dilution.
